Just went through the whole list and disabled them one by one, still getting the same error with every time.
For a little more background info I am using steam to fresh install the game, installing GWX and then using SFSF to move the game files to my D:\Games|Silent Hunter 3 folder.
From there I used S3F to install the 4GB patch and run h.sie patch as well.
Thanks for the quick response, not sure what my next steps will be however, might try to move the game files by hand instead of using the SFSF mod.
